    Muscle Research, Blood Tests To Promote Healthy Crews End Week

    The sun rises above the Pacific Ocean revealing the terminator, the line between night and day on Earth, in this photograph from the Internaional Space Station as it orbited 259 miles above and about 500 miles north of Hawaii.

    Muscle stimulation and blood tests topped the International Space Station research schedule on Friday helping doctors learn how to keep astronauts healthy on long-term missions. The Expedition 72 residents also winded down the work week cleaning spacesuits and life support gear aboard the orbital outpost.

    Vein Scans, Muscle Study on Station Informing Ways to Keep Crews Healthy

    NASA astronaut and Expedition 72 Commander Suni Williams displays production packs containing geneticallly engineered yeast and edible media for incubation to activate yeast growth. The BioNutrients investigation explores using the engineered yeast to produce on-demand nutrients and avoid vitamin deficiencies for crews on long-term missions. The samples are later frozen then returned to Earth to analyze their ability promote crew health and improve the preservation of probiotics.

    Human research, the series of ongoing investigations to understand how an astronaut’s body adapts to living long-term in space, was the main science topic aboard the International Space Station on Thursday. The Expedition 72 residents also continued packing a cargo craft for its upcoming departure and conducted an emergency drill to stay familiar with response, communication, and coordination procedures.

    Keeping Crews Healthy Farther Away from Earth Key Station Research Topic

    NASA astronaut and Expedition 72 Commander Suni Williams (center) is dwarfed near the SpaceX Dragon crew spacecraft as she replaces a planar reflector, advanced navigational hardware visiting vehicles use when approaching the International Space Station. Dragon is docked to the Harmony module's space-facing port which rests in between the Kibo and Columbus laboratory modules. 267 miles below is the Pacific Ocean east of New Zealand.

    The Expedition 72 crew continued its research on Wednesday to better understand space-caused eye pressure changes and ensure crew members stay healthy on future missions to the Moon, Mars, and beyond. The orbital residents also kept up the continuous operations of critical science gear and life support systems on the International Space Station.

    Crew Studies Space Agriculture, Biotechnology to Promote Future Missions

    NASA astronaut and Expedition 72 Flight Engineer Nick Hague processes samples of micro-algae at the Harmony module's maintenance work area aboard the International Space Station. The Arthrospira C biotechnology investigation exposes micro-algae to cosmic radiation and microgravity to learn how to revitalize the spacecraft environment using photosynthesis and produce fresh food on long-term space missions.

    Tuesday’s International Space Station research objectives included learning how to grow crops on spacecraft and produce vitamins and nutrients in space to sustain crews farther away from Earth. The Expedition 72 crewmates also explored how the human body orients itself in weightlessness and serviced a pair of docked spacecraft.702
